The "adaptive" contact syncing app addappt has just received an update that, most importantly, makes the app open to all.
You see, when the app was launched last December, use of addappt was by invitation only. But now, the app, along with everything it has to offer, is available for use by anyone. No invitation code necessary.
But what does addappt do anyway? As Jamie noted in her post about the app following its launch, addappt is designed to "change the way you use your address book, for the better."

The new addappt update also includes the following improvements:
